Templation and Concentration Drive Conversion Between a Fe^II₁₂L₁₂ Pseudoicosahedron, a Fe^II₄L₄ Tetrahedron, and a Fe^II₂L₃ Helicate.

ABSTRACT: We report the construction of three structurally distinct self-assembled architectures: Fe^II₁₂L₁₂ pseudoicosahedron 1, Fe^II₂L₃ helicate 2, and Fe^II₄L₄ tetrahedron 3, formed from a single triazatriangulenium subcomponent A under different reaction conditions. Pseudoicosahedral capsule 1 is the largest formed through subcomponent self-assembly to date, with an outer-sphere diameter of 5.4 nm and a cavity volume of 15 nm³. The outcome of self-assembly depended upon concentration, where the formation of pseudoicosahedron 1 was favored at higher concentrations, while helicate 2 exclusively formed at lower concentrations. The conversion of
